Class HMLabel

java.lang.Object

jhplot.HMLabel

All Implemented Interfaces:

Serializable

public class HMLabel
extends Object
implements Serializable

Create an interactive multi-line label in the USER or NDC coordinates. The label can be defined in the NDC (normalized coordinate system) or the user coordinate For more labels look at the shape package

Constructor Detail

HMLabel

public HMLabel(String[] s,
               Font f,
               Color c)

Make a multitext label

Parameters:

s - Lines of a text

f - Font

c - Color

HMLabel

public HMLabel(String[] s,
               Font f)

Make a multitext label (black color is used).

Parameters:

s - Text

f - Font

HMLabel

public HMLabel(String[] s)

Make a multitext label with default attributes.

Parameters:

s - lines of the text

HMLabel

public HMLabel(String[] s,
               double x,
               double y)

Make a label with specific coordinated in the data system

Parameters:

s - Text

x - Position in X

y - Position in Y

HMLabel

public HMLabel(String[] s,
               double x,
               double y,
               String howToSet)

Make a label with specific coordinates.

Parameters:

s - Text

x - position in X

y - position in Y

howToSet - set it to "NDC" for normalized coordinates (in the range 0-1). This is a data independent position set it to "USER" for the user coordinates

Method Detail

setText

public void setText(String[] s)

Sets the text of the label.

Parameters:

s - new text for the label

getText

public String[] getText()

Get text of the label.

Returns:

the current text of the label

setColor

public void setColor(Color c)

Sets the color to a specific value

Parameters:

c - color used to draw the label

getColor

public Color getColor()

Get color of the label.

Returns:

the color used to draw the label

setFont

public void setFont(Font f)

Sets the font to a specific value

Parameters:

f - font used to draw the label

getFont

public Font getFont()

Get the text font.

Returns:

the font used to draw the label

setRotation

public void setRotation(double r)

Sets the rotation angle. Although all kind of angles (in PI-units) are allowed, internally we only use the interval 0-2pi hence we take care of all other cases.

Parameters:

r - angle for this label

getRotation

public double getRotation()

Returns the rotation angle.

Returns:

angle for this label

seLocation

public void seLocation(double x,
                       double y)

Sets the location of this label in data coordinates. Ones set this way, you cannot plot the label, it must first define the location in pixel-coordinates (setLocation(x,y));

Parameters:

x - x-position of the lower-left corner of the text

y - y-position of the lower-left corner of the text

getPositionCoordinate

public int getPositionCoordinate()

Is the position set?

Returns:

0 if location is not defined 1 if the position is defined in the NDC system 2 if the location is defined in the user coordinates

getX

public double getX()

Returns the X position of the text.

Returns:

the x-position of the text

getY

public double getY()

Returns the Y position of the text.

Returns:

the y-position of the text

getGraphLabel

public jplot.GraphLabel getGraphLabel()

Get a label with default attributes

Returns:

get GraphLabel

doc

public void doc()

Show online documentation.
